How to use unknown JSON key names as my table headers - php

Question

I'm using Laravel framework.
I've got a table with some JSON I want to iterate over, I've cast the table to an array. This is the format;
{"Height": "#m", "Width": "#m", "Weight": {"now": "#kg", "previous": "#kg"}}
My controller returns the view;
$person = Person::find($ID);
$data = $person->tableJson;
return view('person.person_details', compact('person', 'data'));
And in the view itself:
#foreach ($data as $value)
Width: {{ $value->tableJson['Width'] }} <br>
Height: {{ $value->tableJson['Height'] }} <br>
Weight (now): {{ $value->tableJson['Weight']['now'] }} <br>
Weight (previous): {{ $value->tableJson['Weight']['previous'] }} <br>
<hr>
#endforeach
I have that working. The thing is I want to replace the hard coded titles (Width, Height, etc) with the keys in the JSON itself. That way I can (hopefully) dynamically populate a table without knowing what the JSON contains.

When looping your $data use actual keys in that:
$data = [0: ["Height" => "#m", "Width" => "#m", "Weight" => ["now" => "#kg", "previous" => "#kg"]]];
foreach ($data as row) {
foreach ($row as $header => $val) {
if (is_string($val)) {
echo "{$header}: {$val}<br/>";
} else {
foreach ($val as $type => $subVal) {
echo "{$header} ($type): {$subVal}<br/>";
}
}
}
echo "<hr/>";
}
